I own a 1987 Mercedes 190E. A month ago, I
changed all the bushes plus the four shock absorbers
and its mountings which cost me a little more than
RM4,000. The shock absorbers are Bilstein 361389.
I am unhappy as the ride is bumpy and get a thud
noise when going over depressions or potholes. My
feeling is that the shock absorbers may be of the hard
type or the spring coils are "dead". The mechanic said
that he has used the standard shock absorber for the
car and it might be that the coils also need changing.
What is your opinion?
You did not mention what shock absorbers were fitted
to the front but I will assume that they are also Bilstein. The number that you
have given, 36-1389 is for the rear shock absorbers and is actually a heavy
duty unit and that may be the reason why you feel that the ride is bumpy. I think you should be using the "Comfort" specification which is:
I do not think the standard shocks are heavy duty units
and there is no need to replace the springs. I think the
real problem is that the shocks are too hard.
